Consider Using Text Boxes to Communicate. There are a lot of students, especially in middle and high school, that are thoroughly embarrassed when you point out mistakes verbally. I tackle this in two ways: my tone and text boxes. With my tone, I often just blow right through their mistakes as though it is not big deal and with no judgement. I model that with all students. But, if they’ve gotten most of the problems wrong, I don’t call this out in class. Instead, I color them peach and post a text box with a message saying I will pull them into a breakout room very soon to give them a “refresher” lesson. I use the color red so it will stand out. Sometimes it’s just simple messages like the one below.
